BRIEF DESCRIPTION OF THE DRAWINGS
[0002] following detailed description references the drawings, wherein:
[0003] FIG. 1 is a partial schematic view of a device according to an example.
[0004] FIG. 2 is a partial schematic view of the device of FIG. 1 according to an example.
[0005] FIG. 3 is a partial side schematic view of the device of FIG. 1 depicting an output tray assembly according to an example.
[0006] FIG. 4 is a partial schematic rear view of an output tray assembly according to an example.
DETAILED DESCRIPTION
[0007] In the following discussion and in the claims, the term "couple" or "couples" is intended to include suitable indirect and/or direct connections. Thus, if a first component is described as being coupled to a second component, that coupling may, for example, be: (1 ) through a direct electrical or mechanical connection, (2) through an indirect electrical or mechanical connection via other devices and connections, (3) through an optical electrical connection, (4) through a wireless electrical connection, and/or {5} another suitable coupling. The term "connect" or "connected" is intended to include suitable direct connections.
[0008] A number of devices output sheets of media into an output bin or tray for retrieval. The size of output media may vary. The speed at which electronic devices process media has been increasing. For example, printing speeds and scanning speeds of devices are increasing. As a result, media is being output to the output tray at increasing rates. Bail arms have been used to controi media from ejecting off the output tray, in an example, a number of different print jobs or scan jobs with different size media may be output by an eieclronic device to an output tray within a short period of time. However, a user may not retrieve the output media immediately. As a result, baii arms may be used to controi large volumes of different sized media on an output tray. The dimensions of a baii arm may be chosen to controi the smallest sized media output by a device. However, such bail arms may not allow larger sized media to slide underneath or on top of a media stack on the output tray.
[0009] To address these issues, in the examples described herein, a device is described which includes a bail arm to control output media. The device includes a force providing member to provide a counter force to the force of gravity on the bail arm such that a force applied by the bail arm on an output tray is less than the force of gravity on the bail arm. in such an example, the dimensions of the bail arm may be optimized to controi different sized media while allowing the bail arm to supply sufficient force to retain a media stack in the output tray.

Furthermore, it should be understood that the systems, apparatuses, and methods described herein can include various combinations and/or sub-combinations of the components and/or features of the different implementations described. Thus, features described with reference to one or more implementations can be combined with other implementations described herein.
[0021] The above discussion is meant to be illustrative of the principles and various embodiments of the present disclosure. Numerous variations and modifications will become apparent to those skilled in the art once the above disclosure is fuily appreciated, it is intended that the following claims be interpreted to embrace all such variations and modifications.

Claims

What is claimed is:
1. A device , comprising : a bail arm to apply a force to an output bin; and a force providing member coupied to the bail arm to provide a counter force to reduce the force applied by the bail arm to the output bin.
2. The device of claim 1 , further comprising an axle coupled to the bail arm, about which the bail arm may rotate, to transfer the counter force from the force providing member to the bail arm.
3. The device of claim 2, further comprising a pin to couple the axle to the bail arm and to transfer the counter force to the bail arm.
4. The device of claim 1 , further comprising an arm coupied to the force providing member.
5. The device of claim 1 , wherein the force providing member is connected to the bail arm.
6. The device of claim 1 , wherein the force providing member is connected to a pin coupled to the bail arm.
7. The device of claim 1 , wherein the counter force applied by the force providing member is less than a force of gravity applied to the baii arm.
8, The device of claim 1 , wherein the bait arm is comprised of at least one of a carbon reinforced plastics, a glass-filled plastic, a glass-filled nylon, a glass-filled polycarbonate, a glass filled acrylonitrile butadiene styrene (ABS), a metal, a metal composite, a plastic, and a wood.
9. The device of claim 1 , wherein the force providing member is a coiled torsion spring.
10. An output tray assembly, comprising: a bail arm to apply a force to a surface; an axle coupled to the bail arm; and a spring coupled to the axle to provide a counter force to reduce the force applied by the bail arm to the surface.
11. The output tray assembly of claim 10, further comprising a pin to transfer the counter force from the spring to the bail arm.
11. The output tray assembly of claim 10. further comprising art arm coupled to the spring and the axle.
12. The output tray assembly of claim 10, wherein the spring is connected to the bail arm.
13. The output tray assembly of claim 12, wherein the spring is connected to a frame of the output tray assembly.
14. An imaging device, comprising: a bail arm to apply a force to an output tray; an axle coupled to the bail arm; a coiled torsion spring coupied to the axle to provide a counter force to reduce the force applied by the bail arm to the output tray: and a pin to transfer the counter force from the spring to the bail arm, wherein a counter force is less than a force of gravity applied to the bail arm.
15. The imaging device of claim 14. further comprising an arm coupled to the spring and the axle.
